Amplifier Hum

I have a Classe CA-100 that I just purchased and there is a loud hum when I turn on the amp. My previous amp was an Acurus A100, which also had a hum, but not nearly as noticeable. What are some of the root cause of this hum? I assume it is electrical interfernece, but I am not sure from where. Any help is greatly appreciated.

Try using a "cheater plug" on the amp (converts from
three-prong to two-prong). Often a hum is due to
a ground loop and floating the ground will eliminate
the hum.
